Morningstar carbon metrics are asset-weighted portfolio calculations based on Sustainalytics company carbon-risk research. Based on two of these metrics—Carbon Risk Score and Fossil Fuel Involvement %—funds may receive the Low Carbon designation, which allows investors to easily identify low-carbon funds within the global universe.
To receive the Low Carbon designation, a fund must have a 12-month average Portfolio Carbon Risk Score below 10 and a 12-month average Fossil Fuel Involvement % of less than 7% of assets. For these metrics to be calculated, at least 67% of a portfolio’s assets must be covered by Sustainalytics company carbon-risk research. All Morningstar carbon metrics are calculated quarterly.
